The process of the utility model for removing dust from the road is as follows: the driver sits in the cab of the front of the car and drives the vehicle slowly along the road. When the car is moving forward, the drive shaft and the driving sprocket between the two rear driving wheels Rotate, driving sprocket drives driven sprocket to rotate by chain, because the setting of the 4th bearing, driven sprocket only drives the outer ring of driving sleeve and the 4th bearing to rotate. Then press the operation button in the cab to start the exhaust fan, the piston rod of the lifting cylinder extends downward to drive the beam, the sliders at both ends of the beam move down along the left and right guide rails, when the brush on the roller touches the road surface Stop the lifting cylinder; then start the clutch drive cylinder, the piston rod of the clutch drive cylinder extends downward, drives the drive plate to rotate downward, and the drive plate drives the coupling sleeve to rotate. The inner end of the tightening bolt is pressed against the shift fork shaft, so the rotation of the coupling sleeve will drive the shift fork shaft to rotate, and the shift fork sleeve is connected to the shift fork shaft through the connecting bolt, so the rotation of the shift fork shaft drives the shift fork sleeve Rotate a certain angle, the shift fork sleeve drives the lever to turn to the left, the toggle bearing on the lever drives the installation wheel to move along the drive shaft, the fork teeth on the installation wheel are combined with the clutch teeth on the installation sleeve to drive The sleeve will transmit the rotating power to the installation wheel. Since the installation wheel is connected with the drive shaft through the flat key, the rotation of the installation wheel will drive the drive shaft to rotate, and the drum installed on the drive shaft will rotate accordingly. With the rotation of the drum, the brush sweeps back the dust attached to the road surface. Under the action of the exhaust fan, the dust, leaves, paper scraps and other light debris that have been swept up are sucked into the dust collection cover, and after being pumped, After the air duct and the air outlet duct enter the dust collection room in the compartment for storage, after being filtered by the dust filter, the clean air is discharged into the atmosphere.

When the brush does not need to rotate, the piston rod of the clutch-driven oil cylinder can be operated to shrink upwards, and the shift fork teeth on the installation wheel can be separated from the clutch teeth on the installation sleeve. At the same time, the lifting cylinder is controlled to raise the crossbeam upwards so that the brushes leave the ground.

Since the position of the driven sprocket is lower than that of the driving sprocket, the driven sprocket and the driving sprocket are connected by a chain drive. When the beam and the driven gear move downward, in order to keep the chain in tension, the design of the left Both the guide rail and the right guide rail are set with a low rear and a high front height, which ensures that the distance between the driven sprocket and the driving sprocket remains substantially constant when the driven sprocket moves downward until the brush contacts the road surface.

The components of the clutch in the utility model are assembled in separate parts, which not only facilitates manufacture, but also facilitates installation and disassembly.

Since the part of the toggle bolt extending into the card slot is provided with a toggle bearing, when the toggle bearing drives the installation wheel to move left and right, the outer ring of the toggle bearing can rotate with the installation wheel, thereby reducing the size of the inner end of the toggle bolt. Wear between the sidewall of the slot where the wheel is mounted.

In summary, the utility model is novel in design, simple and compact in structure, and can be installed and improved on existing municipal engineering vehicles. In particular, the specific structure of the clutch has unique creativity, which can remove the dust attached to the road surface and the asphalt road surface. The dust in the depression is swept up, and the light sundries such as dust are sucked and stored, and the environment is not polluted during the dust removal process.
